Nike’s Zoom Speed Trainer 3 is a highly advanced, comfortable and lightweight sneaker that was designed with high-performance in mind. The shoe boasts a low-to-ground profile as well as a wide forefoot and heel, and it comes with a special upper that features a breathable circular knit in the forefoot.
This knit ensures directional strength and stretch by expanding in length and width by up to 1.5 sizes when the need arises. The Zoom Speed Trainer 3 is supported by Hexagonal Zoom Air units inserted in the heel, which were designed to provide much-needed impact protection as well as very responsive cushioning. The multi-surface outsole guarantees superior traction, especially when the wearer changes directions frequently.
